The hilarious experience of watching someone interact with a satire but clearly not get it even though it may be an obvious satire.

To the person in question the satire may seem to be the real thing and thus be a case of poe's law. However, to others the satire may seem entirely obvious and they are having a laugh about it. This laugh is poe's lawl.

You ever read some of the comments on the Marijuana makes you violent facebook page? Poe's lawl all up in the comments section.
